A federal judge says he will hold a former USA Today reporter in contempt if she continues refusing to identify sources for stories about a former Army scientist under scrutiny in the 2001 anthrax attacks.

At a hearing Tuesday, U.S. District Judge Reggie B. Walton said that reporter Toni Locy must cooperate with Steven J. Hatfill in his lawsuit against the government.

Hatfill is suing the Justice Department, saying the agency violated the federal Privacy Act by giving the media information about the FBI's investigation of him.

In addition to Locy, the judge is considering whether to find former CBS reporter James Stewart in contempt of a court order requiring the reporters' cooperation in the lawsuit.

Locy also is a former reporter for The Associated Press.
